How do I parallel channels to output higher
current?
Reference Refer to Section 3 of the Series 2600 Reference Manual for details
on SMU connections.
The maximum DC output current of a Model 2601 or 2602 channel is as follows:
• 1.01A @ up to 40.4V
• 3.03A @ up to 6.06V
The maximum DC output current of a Model 2611 or 2612 channel is as follows:
• 101mA @ up to 202V
• 1.515A @ up to 20.2V
Higher current can be output by connecting channels in parallel. Figure B-4 shows
four channels of two Model 2602s or 2612s connected in parallel. Two Model
2602s can output up to 4.04A at up to 40.4V and 12.12A at up to 6.06V, while two
Model 2612s can output up to 404mA at up to 202V and 6.06A at up to 20.2V. The
current delivered to the DUT is the sum of currents output by the four SMU
channels. More current can be output by connecting additional channels in
parallel.
